Extracorporeal shockwave lithotripsy (ESWL) is one way to treat renal stones. In this clinical trial our goal is to evaluate if two ESWL the same week is equal good and safe to two ESWL 3 weeks regarding renal stones 8-15 mm.
All patients with a renal stone 8-15 mm are asked to participate. If they give consent they are randomized to ESWL with an interval of 2 days or 3 weeks. Data regarding age, gender, stone size, Hounsfield unit, skin to stone distance, urine culture, results from the follow up CT and need for auxillary interventions are extraced from the medical records.
